c. AHEARN BATTERY CABLE CONNECTOR Filed Dec. 8, 1938 67/6 1/? IZA'QrW/Invenior Attorneys Patented Dec. 26, 1939 1 Claim.

My invention relates to improvements in storage battery cable terminals,whereby both a strong grip on the battery post and easy removal from thebattery post is produced by mechanical manipulation of a part of theconnector, and an important object of my invention is to provide asimple and efficient and practical arrangement of the characterindicated.

Other important objects and advantages of my invention will be apparentfrom a reading of the following description taken in connection with thedrawing, wherein for purposes of illustration I have shown a preferredembodiment of my invention.

In the drawing:-

Figure 1 is a top plan View of a portion of a storage battery showingthe device of the invention connected thereto.

Figure 2 is a side elevational view of Figure 1.

Figure 3 is a horizontal sectional view taken through Figure 2approximately on the line 3-3.

Figure 4 is a horizontal sectional view taken through the upper part ofFigure 5 and approximately onthe line i4 and looking downwardly.

Figure 5 is a transverse vertical sectional view taken through Figure 1approximately on the line Referring in detail to the drawing, thenumeral 5 generally designates the embodiment of the present inventionwhich comprises two substantially semi-cylindrical sections respectivelydenominated by the numerals 6 and 7. Each of these sections hassemi-annular laterally outwardly projecting portions affording therespec- 35 tive shoulders 3 and 9 on which the rotary cam bears, thesesections also having the L-shaped flanges ll, 12, respectively, whichoverlie the shoulders 8- and 9 and confine the rotary cam ill in place.The section 1 has projecting radially therefrom below the shoulder 9 atubular arm 53 which is adapted to be telescoped on and secured to theterminal of the battery cable l4.

The terminal edges of the section 6 have aligned ears l5, l6 whichproject therefrom along and at the inner side of ears I1, H3 projectingfrom the section 1 in a position circumferentially outwardly spaced fromthe ears 15, I6, and suitable pivots such as rivets i9, 20 traverse thereter thereof and is equipped with a turning handle 23. A stop post 24projects from the section H at the top thereof to be in the Way of oneor the other end of the handle 23 so as to limit the rotating action ofthe cam in either'direction beyond a full rotation thereof.

The grooves in the sections 6 and ldefined by the L-shaped flanges I land i2 and the shoulders t and 9 are formed on such radii of curvature,and the sections so spaced with respect to each other that when the longaxis of vthe cam it lies along the opening between the sections thesections are permitted to tilt toward each other at the top thereof asillustrated in Figure 5 and thereby spread the bottom of the sections toreadily and easily receive the battery post 25 on the battery it.Therefore, with the connector installed on the battery post turning ofthe handle 23 to bring the cam into the stated position will operate torelease the sections from clamping engagement with the sides of thebattery post so as to facilitate removal of the; connector from thepost. On the other hand, the connector having been installed with greatease on the battery post 25 because of the spread of the lower ends ofthe sections of the connector, the sections are brought into clampingrelation with the sides of the battery post by operating the handle 23to bring the cam out of alignment with the opening between the sectionsand into a turned position such as illustrated in Figure 4, wherein theends of the cam bear against the grooves mentioned and force the tops ofthe sections away from each other on the axis of the pivots l9, Zllandthereby force the lower part of the sections forcibly against the sidesof the battery post so as to effect an efficient clamping action.

Although I have shown and described herein a preferred embodiment of myinvention, it is to be definitely understood that I do not desire tolimit the application of the invention thereto, and any change orchanges may be made in the structure and arrangement of the parts,within the spirit of the invention and the scope of the subjoined claim.7

Having described the invention, What is claimed as new is:

A battery cable connector comprising a pair of semi-cylindrical membersfor fitting around a battery post, means for connecting a cable to onemember, each member having a flange-like enlargement at its upper endformed with an internal groove, one member at the substantial centralportion being thicker than the other member and said thickened portionhaving internal recesses at its edges, ears extending outwardly fromedge portions of the other member and said ears extending into therecesses, the recessed portions of the thick member forming ears whichoverlap the first-mentioned ears, pivots pivotally connecting the earsof the two members together,
